High Altitude Sickness

Acute Mountain Sickness(AMS) is common at high altitudes, and depends on the elevation, the rate of ascent and individual susceptibility. Most visitors to Tibet will suffer from at least some symptoms that will generally disappear through acclimatization in several hours to several days.

Symptoms tend to be worse at night and include headache, dizziness, lethargy, loss of appetite, nausea, breathlessness and irritability. Difficulty sleeping is another common symptom, and many travelers have trouble sleeping for the first few days after arriving in Lhasa.

To prevent acute mountain sickness:

Drink extra fluids. The mountain air is dry and cold and moisture is lost as you breathe. Evaporation of sweat may occur unnoticed and result in dehydration. Eat light, high-carbohydrate meals for more energy. Avoid alcohol as it may increase the risk of dehydration, and don¡¯t smoke. Avoid sedatives. Don¡¯t push yourself when climbing up to passes, rather take plenty of breaks. Avoid catching cold before you entering Tibet.

We suggest clients who suffered from high blood pressure and severe heart disease not travel to Tibet.
